The Cascade Range in Washington, Oregon and northern California is composed of volcanic mountains. Some of the largest volcanic mountains are found along divergent boundaries, which form the mid-ocean ridges. The mid-ocean ridges have huge volcanic mountain chains that run through the Atlantic, Pacific and Indian Oceans. The mountains in the mid-ocean ridges can actually grow tall enough to create islands such as Iceland or the Azores.Other volcanic mountains can form over hot spots, which are pockets of magma beneath the crust that erupt onto earth’s surface. The Hawaiian Islands are actually the tops of really high volcanic islands that have formed over a hot spot on the sea floor. The main Hawiian island is actually a volcano that is about 9 km above the ocean floor, with a base that is about 160 km wide. Almost 4 km of this is
